Blendtec FourSide Jar The Original Square Jar is rated 4.5 out of 5 by 78.
Rated 5 out of 5 by from Great upgrade of original container I've used Blendtec blenders for the past 10 years or so, and while I always liked the fourside jar, I was unhappy with both the container material and the bearings of the blade. This new container fixes both problems. The material is a clear and doesn't seem as vulnerable to etching as the original containers. The blade assembly and bearings are amazing -- quiet, sturdy, and apparently so well designed the jar comes with a 3-year warranty, or longer if you're buying it as part of a blender purchase. This is the last thing that might have kept me from recommending the Blendtec blender to everyone. I'm completely satisfied with the way it works and looks.

Rated 5 out of 5 by from Smoothie time commences My Blendtec is four years old and recently the o ring seal decided to start throwing bits of rubber into my smoothies! Pretty disappointing considering the cost of the blender (and the fact I had to buy a whole new jar instead of repairing the old one) but oh well, worth it because I drink smoothies about 5 times a week and nothing blends better than a Blendtec. It WILL blend!

Rated 5 out of 5 by from Love the new lid design I bought this just to replace my original, which, after six years, shattered when I was running the blender. I guess it just gave out. The new lid design is great! It really stays put. There is no leakage and it seems like it stays cleaner during use than the old one did. For example, with the old lid, when I ground coffee, the inside would be covered in coffee grounds. Now, it's pretty clean and I can just rinse it off.

Rated 3 out of 5 by from Keep having ot replace jars I found out after I purchased these jars "on sale" that I could have bought a new Blendtec for about $20 more at Costco. These are the last jars that I will buy. I am done with this product.

Rated 4 out of 5 by from great jar, less than great lid I just bought a new jar -- the old one was leaking after 6-7 years (thanks for the great product!). It's very lucky that my old lid is as good as new (thanks for the great product!), because it's so easy to scrape the smoothie goodness off it with a scraper, unlike from the newly-designed lid. The latter has narrow and curved rut, which requires a small, narrow object to do the job. I don't have such an object; a tea spoon doesn't do a good enough job. I tried the new lid a couple times but eventually shelved it in frustration. I wonder if other folks give similar feedback and if BT would consider going back to the old design in future iterations.

Rated 5 out of 5 by from Operator who completed my order was a delight Purchased and had difficulty getting discount code to work, order went through without it, agent then helped and assured me after systems are back up would make sure discount was given, as promised this was done much to my satisfaction, love that I was taken care of in this way plus she was so nice...

Rated 5 out of 5 by from Love the smaller size I bought this a month ago for smoothies in the morning. It’s perfect for it.

Rated 1 out of 5 by from Chunky blend! I bought this jar a year ago and I have been very unhappy with it. It does not blend smooth, does not stay sealed (yes it broke open and exploded all over) and leaves chunks. I have tried all of Blendtec's ideas of how to make this work better but it does not fix the problem. Don't waste your time! Ive even had this exact jar replaced once because the first just fell apart in the bearing. Get the wild side (wish I could but it is not economical to buy another jar). Not happy with it!
